The Pentagon’s research agency, the Defense Advanced Research Projects Agency (DARPA), also anticipates slashing small satellite payload costs from more than $30,000 per pound to less than $10,000 per pound — making such launches three times cheaper. . . . DARPA wants the program to demonstrate at least 12 launches of 100-pound payloads to low Earth orbit, with each launch costing about $1 million. Launches could start as soon as 2015, according to DARPA’s official announcement of the program on Nov. 4.

At first glance this appears to be good news for Orbital Sciences and its Pegasus rocket, the only commercial launch system that has successfully put satellites into orbit using a commercial L1011 airplane as its first stage. At the same time, however, it appears DARPA is pushing for new technology to lower costs below what Orbital charges, meaning the game is open to anyone.

Orbital Sciences has announced its revised schedule for the initial Taurus 2 and Cygnus flights.

Orbital will conduct a test of the Taurus 2’s first stage on the launch pad in late January [2012], and the inaugural Taurus 2 flight in late February or early March. This will be followed, in early May, by a Taurus 2 flight carrying the Cygnus station cargo vehicle, a flight during which Cygnus is expected to demonstrate its ability to berth with the station. The first operational space station cargo-delivery mission for Taurus 2 and Cygnus will occur in late August or early September under this revised schedule, Orbital officials said.

Based on conversations I’ve had with people at Orbital, this delay was expected, and is a good thing. The company was under incredible time pressure to get ready for a December launch. Given that this will be the first test flight of Taurus 2, and it must work for the Cygnus cargo flights to follow, better they give themselves some working room to get it right.
